Hey everyone, I am a Galaxy Nexus user but my brother got an old Roger's S2 LTE that he wants to put on a non-Rogers network (same one I am on with my GNex). However we are having a weird issue where if we insert the original (deactivated) SIM that came with the phone it detects it. But if we put in either mine or his own it just always says "No SIM Card". I even have a pay as you go AT&T SIM that wont work in it either. So far I have flashed CyanogenMod and tried the UCLF6 radio as well as the Rogers ICS Radio UXLF3 from this thread http://forum.xda-developers.com/showthread.php?t=1754473
I should note that when my brother originally inserted his SIM he got the unlock screen and paid to unlock it through cellunlocker.net and it was recognizing his SIM at that point. Since then however we have had no luck. He even replaced the SIM card board with a new one.
Any ideas? I am leaning towards hardware issue but its odd that it still reads the original inserted SIM
did you try to go back to stock firmware and see what happened
Yep. I'm pretty sure its hardware. I got it to read again but still no signal. I have it reading my AT&T card now but again still no signal.
In fact even without a SIM card in if I search for Network Operators nothing comes up. If I do the same on my GNex I get a listing so its looking like this phone is no good
EDIT: Just realized who responded. Your threads were VERY helpful for me! Thanks so much... I'm still not convinced the phone is toast... I have a friend with a GNex on Rogers (I'm on MTS) so I will see if I can borrow his SIM and see what happens

agree, not the phone, the only way to make sure of anything is to restore to stock and do all the testing from that point on
edit: dah, its the radio, what freq is the new sim card on that wont work, is it the same as T-Mobile
edit: maybe not radio, think its like rogers, could be network settings
Actually both MTS and Rogers use the same towers so the phone should be set properly.
I've got it reading my MTS SIM now but cant pick up any networks. Its set to LTE/HSPA/GSM (Auto) and MTS is HSPA.
Is there anything that could be done to the IMEI of the phone to sort of "blacklist" it from working on any network?
Here is where I have tested from so far:
Stock before I did anything to the phone (Stock rogers GB)
CM9 Nightly
Stock Rogers ICS
SkyICS
I have also tried both the lastest AT&T Radio as well as the latest Rogers Radio. With my GNex both myself and my friend on Rogers use the same Radio (UGLC1).
At this point it seems either the radios arent working at all or the phone is blocked somehow
EDIT: Info on the MTS network... Found on the FAQ on their site:
Any unlocked devices (i.e. devices that are not tied to a specific carrier) will work with MTS SIM cards (on the MTS 4G network). However, carriers such as Rogers, Bell and Telus lock their devices to work with only their SIM cards and these devices will not work with a MTS SIM card. Similarly, MTS intends to lock our devices to our SIM cards. Therefore, our devices will not be usable on another carrier's network.
Please note that any unlocked device must support 4G North American Frequencies (850Mhz), older GSM devices will not function on our new 4G network. You can find out if your device is 4G compliant by reviewing the phone's settings.

UGLC1 never seen that radio for the skyrocket
edit: oh, for the gnex
did you try the *#2263# menu
Yes when I try that menu (*#2263#) it doesnt do anything. I can do *#*#4636#*#* when on CM9 and it works but on stock and SkyICS it just FCs when I select "Phone Information"...
I am going back to Rogers Stock ICS right now. Gotta head off to my engagement party but will likely be back at it tomorrow
shouldn't forceclose, redl and try reflashing x2 the rogers radio, wipe/format x3 in cwm b4 going back to stock ics
Will do first thing tomorrow (or tonight if I'm still in any shape to do so )
If anyone reading this thread has a stock Rogers phone can you turn it off, take out your SIM and then boot it up without a SIM in it and then do a Network Search and see if anything comes up? On my GNex I get networks but on the S2 LTE I dont. In fact I have never seen any signal from any network on this phone yet with an MTS, AT&T and an old Rogers SIM
EDIT: Actually you will probably have to be on CM9. With stock you cant get to the Network Operator section without a SIM card inserted but in CM9 you can

Ok I had enough time to do as you suggested above. Wiped like crazy then went back to stock using the ODIN method and the firmware from sammobile.
Actually I figured it out... it only FCs when I have the AT&T SIM card in and I think thats because AT&T is RAT Locked? If I have no SIM in I can get to all the menus.
k, try to set the freq(play around with it) in that menu w/out sim, then shutdown and install sim b4 restarting, left haptic to click "end" is saving
Got home and went right to work. Almost positive the problem is the radio not working now. I managed to get both SIMs reading without issue but neither will get signal of any sort (even straight after stock reflash). Gonna call it for now until I get a hold of my buddys Rogers SIM.
Thanks so much for all the help, I really appreciate it!
I'm not sure if I'm going to find an answer to this question since there are at most a dozen Photon Q's being used with Bell Mobility up in Canada, but you never know until you ask right?
Just got CM 10.1.3-RC2 (Android 4.2.2) up on my phone, and it's working great with one exception: I'm not being notified when a voicemail message is waiting for me.
I've been looking around and haven't seen anyone else posing this question in relation to the Photon Q, though there have been a few other post around for other phones. However, the suggested answers seem to vary by phone: the HTC Desire Z supposedly needs a radio update, many phones (all?) had issues with CM7, the Inspire 4G apparently needs a bit of specific code., etc...
Does anyone have a solution to this for the Photon Q?
I would love to know how you managed to get Bell's service on your phone, as it doesnt show up properly in their MEID database and they cant give me a straight answer before I use my credit card.

Hey unfortunately I never got this sorted out. I'm now running 4.3 and still having the same problem. For me it's not too much of an issue as people rarely seem to make phone calls these days, but I just kind of check my voicemail manually every few days just to be safe.
But you still have voice/text working? I tried bringing it to a Bell store today and they couldn't activate it without a certain hexadecimal 11-key number that's unique to the device.

I do have voice, text, and all the other stuff working just fine. I didn't even talk to Bell about "activating" my device, I just took the sim card out of my old phone and put it in the new one, and voila. However, I believe it depends what rom you're running... I'm using CyanogenMod and I believe they include some specific settings to get the phone up on various carriers.
Sorry if this is an obvious question, but you've done the hardware mod needed to use a Canadian (or other) SIM card right?
Basically everything I did I found in a single thread: http://forum.xda-developers.com/showthread.php?t=1929143 It's a long one but chances are you'll find what you need to know somewhere in there!
Ah, I thought you were using their CDMA network. Trying that route before having someone do the mod for me. I'm thinking the key might be the MIN.
With GSM it's easy - you take out your SIM card, and you are off that SIM's network.
Presumably the Nexus 5 will work for voice and 3G without the SIM card. Is there some way to turn off CDMA (yes, I know that if there is no SIM I can just turn off all cellular data. But that's not my question.)
If you mean temporarily, you can always do the old standby of airplane mode. Enable airplane mode, then enable whatever wireless services you want (Wifi, Bluetooth). The airplane mode will keep the cellular modem completely off.

Now that the phone has been out in the wild for a while does anyone know the answer to this question?
The N5 does not allow voice or 3g without a sim for some reason. Perhaps someone will figure out a way to bypass this check at some point.
You can also pick and choose between gsm only, cdma only, lte only etc no problem.

So if you take out the SIM, and you are on Sprint, you can't make phone calls or use 3G data?
I know the Sprint LTE Iphones will work if the SIM is removed, just without LTE.
Maybe that's just a way of keeping things clear to the user - your phone has the identity of whatever SIM you have in at any given time.

I don't think it is compatible with any other CDMA only provider - certainly not with Verizon. Who else is there? Metro is going GSM/LTE.
Or perhaps the SIM is necessary to pick the CDMA provider - most CDMA phones are carreir specific, and they just default to the carrier associated with the phone. In other words, if you turn on an unactivated Sprint or Verizon phone, it automatically goes to the correct carrier. If the Nexus 5 has access to more than one CDMA carrier, perhaps the SIM is the method of selecting the carrier.

PagePlus is one who runs on Verizon and allows any phone. No LTE tho with them.
Also, The carrier on most CDMA phone is determined by the PRL file. This tells the phone which towers to communicate with and it can be changed.

Presumably then the PRL is preloaded on the Nexus 5 - hence it knows to look for Sprint.
I believe Page Plus as a Verizon MVNO and will only activate Verizon phones, or their own (Page Plus) phones.

They will activate any CDM phone for a except few exceptions such as if the phone is ESN banned on Verizon, PrePaid Verizon phones, Verizon iphones and Verizon blackberry devices. It's a well known unofficial policy.
To add backing of this you can see my signature
Due to hearing that problem I might look at a S4 or something. I generally like the build quality of Samsung much better than LG.

Interesting, but doesn't really make sense that 3G data is unavailable. If you put a GSM LTE SIM in and select CDMA only, will it make calls on Sprint? (Don't mean to tell you what to do, but I think it would be an interesting thing to find out if you were so inclined.)

Well, that might be an interesting back door into Verizon. I wonder if there is some way that the Nexus 5 can be flashed or otherwise work on Page Plus. I get there would be no LTE, however.

I guess I really don't understand how CDMA works. With GSM, if the phone is unlocked, it works on any network. CDMA always seems to involve flashing. Although I believe there is so me sort of lock on CDMA phones as well (after all, MSL = Master Subsidy Lock.) I wonder if the CDMA side of the phone is locked to Sprint (we know from other posts there is an MSL code for these phones.)

In my experience, none of the *#*#xxxxx#*#* codes work without the SIM inserted. You might even need to be activated on Sprint at the time.
Just to clarify, CDMA in this thread includes WCDMA(3g) too?
So the phone will either go GSM or LTE only, which 3g or HSDPA/HSPA are not available by options?
I bought a used XT897, did the SIM mod, and run it with AT&T, a GSM/UMTS provider. I'm wondering if I can *also* activate it with a Sprint MVNO like FreedomPop or Ting and somehow use both services alternately / at the same time, i.e. like Chinese phones with dual SIM slots. Has anyone explored this?
I'm currently running a 4.2 version of Cyanogenmod, and they split their distribution into separate UMTS and CDMA builds, so I'm guessing I'd either have to alternate between OS backups, or I'd have to simply switch to another distro / the orginal Sprint 4.1.2 Android...

I actually have exactly the same question.
I tried to ask LG/Samsung tech support, but either they really don't have a phone capable of that, or just don't know the answer.
I guess, it may be a matter of software supporting that as some phones (like LG G Flex 2) have radios capable of doing both.
But my feeling the 'stock rom' is only doing it in 'roaming' mode, when original provider can still get some money for the calls.
I like RingPlus and Truphone but I hate to carry 2 phones at the same time. This really sucks.
Anyone knows the answer to this thread's question?

From my experience, you can only switch between CDMA and GSM modes, so only one provider can be active at a given time. I'm using a SIM-modded Photon Q running CyanogenMod 12.1 on Ting CDMA with a FreedomPop data-only SIM card (using AT&T or T-Mobile signals) inserted. I occasionally switch to GSM to use free data on FreedomPop when traveling, at which point my CDMA phone number is essentially turned off until I switch back to CDMA mode.
My guess is that you'd need a phone with both CDMA and GSM radios that also has dual SIM card slots, which, at least in the U.S., would be difficult to find.
hi...not possible...power amp is only one and phone is maded only for one sim work.

I flashed the crDroid ROM onto my stock g7 Power, no problems. Flashed gApps and Magisk, everything ok. I did all of this while the device was unactivated and with the SIM card not in it. Everything works fine. But when I activated the device on the Sprint network and inserted the SIM card, I get no data. I know people have said you can manually edit the APNs in the Mobile Network settings, but the problem for me is, there is no APN option in that menu. However, when I remove the SIM card, I DO see the APN settings option there, but of course the whole menu is grayed out because the SIM card is removed. Has anyone else been able to customize and root one of these phones for use on the US Sprint network? Should I use a different ROM? Any suggestions would be helpful.

Hey there... This is just a possibility...
A while back, I put my sister's CDMA sim into a custom Rom-ed phone. Couldn't add an APN for the life of me. And then, duh , it turns out it was because the phone radio was set on LTE/UMTS (auto)... Is your radio set for LTE/CDMA?

Turns out it was on "LTE/CDMA/UMTS auto (PRL)". I changed it to "LTE/CDMA auto (PRL)" which is what the Sprint network uses, I'm pretty sure. That did seem to change some things, but I still don't see any APN settings and I still don't have data, unfortunately.* I think this ROM is just not set up to work on the Sprint network? Maybe I'll try flashing a different one.

Did you ever get it going? When I install Pixel Experience + I have no apns at all. Not in system/product/etc or product/etc which is where they are supposed to be located. So I just paste apn.conf.xml in the system/product/etc and set 0644 then go to networks and internet/mobile networks/access point names and hit reset to default and data's on , reboot afterwards and it's all fine. What's your model # on your device? Also are you sure your sim card isn't damaged? When they crack sometimes it's impossible to see with the naked eye. And technically you're not on Sprint anymore you're on T-Mobile because they finally finished the deal and Tmo now owns Sprint. (Which is a really good thing imo) ;p if and when you do get your issue resolved be sure and save your apn.conf.xml and upload it to Google drive or something so you'll have it if you need it again. I noticed that the first APN xml files I linked you to I had apn.config.xml for the name and that's not correct supposed to be apn.conf.xml My bad on that. Sometimes I drink a lot of coffee.

Please tell me more about CDMA also using GSM because they are two different technologies.. CDMA was used by USA military back in ww2 to send messages safely and GSM is what most the world uses. CDMA has always been more of a USA tech while GSM has always been pretty much what everyone else uses. They both send information in different ways. They do not work the same or together far as I know.
If you want to be more compatible with development use a GSM carrier like Metro, T-Mobile because GSM is what still rules the world far as phone tech goes. And we here in the USA only make up a small piece of the world far as development goes.
